Technical specifications are based on the supplied equipment information and published model specifications. The actual machine configuration, machining accuracy, operating condition, tooling, and accessories should be confirmed before purchase. The 0.1 μm value refers to the minimum CNC command increment, not guaranteed machining accuracy.

Applications of the Used SEIBU SNC-28Pi CNC Lathe

Used SEIBU SNC-28Pi is designed for precision turning of small metal components, particularly where compact machine construction and repetitive machining operations are important.

Typical applications include:

Precision shafts, pins, and bushings
Small valve components and sleeves
Metal connectors and precision fittings
Automotive and electronic mechanical components
Small cylindrical parts for industrial equipment
Repetitive precision turning operations

The gang-type tooling arrangement allows short tool-to-tool travel, while the rigid machine structure is designed to support dimensional stability during machining.

Actual suitability depends on workpiece material, dimensions, tolerances, tooling, and the condition of the used machine.

FAQ

What CNC control system does the SEIBU SNC-28Pi use?

This machine is equipped with a FANUC Series 32i-MODEL A CNC controller. The system is used to control precision CNC turning operations and X/Z-axis movements.

What types of precision parts can the SEIBU SNC-28Pi machine?

The SNC-28Pi is designed for small precision-turned components, including shafts, pins, bushings, valve parts, sleeves, and metal fittings. Machining suitability depends on the workpiece material, dimensions, tooling, and tolerance requirements.

Can this used SEIBU SNC-28Pi achieve 0.1 μm machining accuracy?

The machine has a minimum CNC command increment of 0.1 μm, but this does not represent guaranteed machining accuracy. Actual precision must be evaluated according to the machine's condition, tooling, setup, and inspection results.
